Metal seems Strong and sturdy so far. Good hardware too when assembling. Easy to assemble. Used for a young grape vine. It’s beautiful and looks great in my yard and very wide which is nice. Took away one star because the pieces have plastic caps on the ends to keep water out but some of the caps keep popping off, so not sure if that will play a role in rust down the line or not.  If it wasn’t for that I would put 5 stars. If It later rusts or doesn’t hold up well I will change my review.
